If you level with friends Prot would probably be the way to go so you could pull and face tank the packs. I leveled 2 pallies both ret on beta and had 0 issues. Selfless healer and wake of ashes work absolute wonders. I leveled a bit as prot and just felt like I did 0 damage. I leveled solo so I don’t know about the xp fall off but I would assume it’s the same as legion.
That means, if real players value their time at least as much as gold-sellers value a bot’s time, tokens should never be as cheap as illegal gold. But if it becomes as cheap to buy gold from other players than it is to buy it from gold-sellers, the players who patronize illegal services will switch to tokens. That means more tokens in the market, and therefore, lower prices, so the gold-seller price should impose a ceiling on WoW Token prices.
Congratulations on reaching Level 120! There are a myriad of new things to do. The first thing you should do is head to your faction hub ship where you have been doing your mission table quests and footholds to pick up and complete the quests necessary to unlock World Quests. World Quests will provide you an opportunity to grind reputation levels, acquire gear, and gather Azerite. There are tons of new things to do that we will cover in our Level 120 Battle Guide found here: Level 120 Battle Guide
